[SERIOUS] Actual use cases that could be organic to the space?

Which projects do you feel have actual use cases that have a chance of altering the space in a significant sense. I understand layer 2s and zkEVM rollups. Those to me are not space altering. I understand those that have almost $0 cost to use (nobody cares on a big enough scale). What projects are attempting to provide a use case that would improve on the store of value concept and or has some form of interoperability that could realistically be crucial in moving this sector forward.

I was wondering if there are any unique pro arguments for any coins you follow that aren’t just money grabs.
